PI7C9X3G816GPQ3HFCE

Overview

The PI7C9X3G816GPQ3HFCE is an automotive-grade PCI Express 3.0 packet switch manufactured by Diodes Incorporated. It features 8 ports and 16 lanes, operating within a temperature range of -40°C to +85°C. The device supports up to 15 endpoints and includes 8 physical DMA channels. Power consumption is rated at 4.1W with a typical latency of 150ns. It utilizes a 324-pin HFCBGA package (19mm x 19mm) and complies with AEC-Q100 Grade 3 standards.

Feature Summary

• Configurable upstream and downstream port assignments with elastic bifurcation capabilities
• Integrated PCIe Gen3 clock buffer supporting common, SRNS, and SRIS reference structures
• Advanced signal integrity management including adaptive equalization for channel loss exceeding 30dB
• Comprehensive RAS features including end-to-end data protection and error handling mechanisms

Applications

• Automotive Zonal Central Controllers
• Advanced Driver Assistance Systems (ADAS)
• In-vehicle Telematics units
• Infotainment systems
• Cockpit Control modules

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. Confirm that the component meets AEC-Q100 Grade 3 requirements for your target application. Ensure compatibility with IATF 16949 manufacturing standards if required by your supply chain protocols.

Selection Notes

Select this model when 8 ports and 16 lanes are required for automotive PCIe 3.0 networks. Consider the HFCBGA-324 package dimensions for PCB layout constraints. Evaluate power budget requirements against the 4.1W specification. Verify thermal management solutions for the -40°C to +85°C operating range.

Part Context

This component belongs to the Automotive PCIe 3.0 Packet Switch family, which also includes models with 6, 8, and 32 lanes. It shares architectural similarities with other members but offers specific lane and port configurations tailored for high-performance automotive networking applications requiring multi-host support.

Replacement Considerations

PI7C9X3G816GPQ3HFEX is a tape-and-reel variant of the same functional device. Other family members like PI7C9X3G808GPQ offer fewer lanes. Verify pinout and package compatibility before substituting with non-family switches.
